ANTISCALDING-VALVE.

Specification of Letters Patent.

Patented J an. 2,1912.

To all whom it may concern:

e it known that I, ROBERT H. BRYON, a citizen of the United States, anda resident of Bay Ridge, in the county of Kings and State of New York,have invented certain new and useful Improvements inAntiscalding-Valves, of which the following is a description.

The present invention relates to valves and has particular applicationto a device of the type referred to, commonly known as an anti-scaldingvalve.

In carrying out my invention, I have in contemplation the provision of avalve provided with hot and cold water connections and so constructedthat when it is operated to permit the water to flow, the cold waterwill issue at the point of discharge before the hot water passes throughthe valve, thereby obviating the possibility of scalding.

To the accomplishment of the above recited object and others of asimilar nature my invention consists in the construct-ion, combinationand arrangement of parts set forth in and falling within the scope ofthe appended claims.

While I have herein shown and described one embodiment of my invention Iwish it to be understood that I do not confine myself to all the precisedetails of construction as there may be modification and variation incertain respects without departing from the spirit of my invention orexceeding the scope of the claims.

In the accompanying drawings wherein I have delineated one embodiment ofmy valve, Figure 1 is a vertical longitudinal sectional view of a valveembodying my improvement; Fig. 2 isa vertical sectional view of the sametaken transversely through the valve; Fig. 3 is a longitudinal viewpartly in elevation and partly in section showing the valve open topermit the full flow of thehot water; Fig. 4 is a cross sectional viewtaken on the line 44 of Fig. 3; Fig. 5 is a similar view taken on theline 55 of Fig. 3; Fig. 6 is a detail view, partially in sec tion, ofthe valve stopper and connected parts; Fig. 7 is a sectional view takenon the line 77 of Fig. 6.

Referring now to the accompanying drawings in detail, the letter Aindicates the valve body as a whole, having a cold water inlet 5 and ahot water inlet 6. This hot water inlet has achannel 7 provided with andterminating in a vertical tubular extension 8, extending approximatelycentrally upward into the chambered portion of said valve, the upperedge of said tubular extension being inwardly inclined as is shown at 9,to form a bearing surface for the disk 10, which is preferably formed ofrubber or similar material and is connected to and forms a part of thevalve stopper, which latter I have indicated as a whole by the numeral1'1.

At 12 I have shown an annular wall flange extending inward from the bodyof the valve, said flange having its upper edge portion beveled as at13, and upon such beveled portion is designed to be seated the gasket orring 14 preferably of the same material as the disk 10, said ring beingsecured to the main portion of the stopper by means of the bindingcollar or ring 15, threaded onto the body of the stopper, said ringhaving its lower end extending slightly inward as at 16, to form a smallretaining flange for the seat ring or gasket.

The valve stem, which is indicated at 17, passes downward through thevertical extension 18 of the valve body, which extension has itsinterior wall threaded as at 19, to receive corresponding threads 20formed on the enlarged caplike portion 21 of the valve stem. The valvestem is also formed with a short flanged stud-like portion 22 designedto be connected with the valve stopper 11 by means of the flanged coupling 23 threaded onto the extension 2-1 of the stopper 11.

Depending from the stopper body is the thimble 25 which is in the natureof a comparatively long tube and is adapted to telescope with andsurround the vertical extension 8 of the hot water inlet. This thim bleis formed with a plurality of graduated apertures or 'openings 26through which the hot water is adapted to issue on its way to the outlet27 said openings being arranged in any preferred and convenient order.At its lower free edge the thimble is outwardly flared and beveled as at28 so that when the valve is moved to permit the full flow of hot waterthrough the outlet opening, the flared edge 28 will bear against theunder surface of the annular flange 12 and diminish the supply of coldwater from the outlet.

The upwardly extending tubular portion 18 of the valve is formed with acap 29 having a stufling box 30 arranged therein through which stuffingbox the stem passes, said stufling box being surmounted by a second cap31.

The handle for turning the valve is indicated at 32.

From the above description taken in connection with the accompanyingdrawings the construction and operation of my improved anti-scaldingvalve will be readily apparent. In the position shown in Fig. 1 the flowof both hot and cold water is entirely cut off, the valve disk 10 andthe ring 16 resting upon their respective flanges. Now if the handle 32be turned to the left the valve stopper will be elevated and cold waterwill be permitted to flow through the inlet 5, the passage 5 between theextension 8 and the flange 12 into the body of the valve and then outthrough the outlet opening 27 to a shower or the like. If the turning ofthe handle to the left be continued, the thimble will gradually riseuntil one or more of the openings 26 comes above the top edge 9 of thehot water inlet extension 8, when the hot water will begin to flowthrough such openings into the valve chamber and through the outlet. Ifthe turning of the handle 32 be then continued until the flared end 28strikes the annular wall or flange 12, the flow of cold water will bepartly cut off and the full flow of hot water be permitted through theopenings 26.

It will be apparent that I have provided an eflicient anti-scaldingdevice adapted particularly for use in houses and establishment-s whereit is necessary to have a large supply of hot water always at hand,minimizing the possibility of persons using the device scaldingthemselves, as the device is constructed to have the cold water flowfirst, while the full force of the hot water is not attained until thevalve stopper is elevated to the limit of its upward movement.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A valve having an inlet terminating in an extensioncentrally of the interior of the valve, a second inlet, and means forcontrolling the inlets comprising a stopper member having a tubularmember outside of and telescoping with the central extension, saidtubular member being provided with an outwardly extending projectionadjacent the lower end thereof.

2. A valve provided with an inlet passage, a second inlet passageadjacent thereto, a stopper having a centrally disposed disk adapted torest upon and entirely close'the first-mentioned passageway, suchstopper also having a thimble extending from the stopper around saidcentral disk and formed with perforations of different sizes, and arimlike member carried by said stopper and adapted to rest upon andentirely close the second passageway.

3. A valve having a plurality of inlet passages, an outlet passagecommunicating with said inlets, and a stopper having a perforated memberadapted to control the flow through one of said inlets, said perforatedmember having a projection thereon adapted to prevent the flow of fluidthrough another of said inlets when fluid is passing from the firstinlet through the perforated member.

4. A valve having a plurality of inlets, an outlet, and means forpreventing the flow of fluid from the inlets to the outlet, said meansincluding a stopper having a depending perforated member adapted toclose one of the inlets when a second inlet is open to the outlet andprovided with a flaring end portion adapted to close said second inletwhen the first mentioned inlet is open to the outlet.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
